What a green card is and the main paths to get one

A green card is permanent resident status in the United States. It lets you live, work, and study here without a visa sponsorship, and it's a step toward citizenship. The application process varies dramatically depending on how you're immigrating — through family, employment, diversity visa lottery, refugee or asylee status, or other routes — and each path has different forms, wait times, and requirements.

There is no single "green card application." Instead, you follow one of several distinct processes, each with its own USCIS forms, supporting documents, and approval timeline. Some routes require a sponsor (a family member or employer). Others don't. Some involve consular processing abroad; others happen entirely in the United States. Understanding which path applies to you is the first step, because filing the wrong form or following the wrong process wastes months and money.

Key Takeaways

  • Green card pathways differ by family relationship, employment, diversity visa, refugee status, or other categories — each with separate forms and timelines.
  • Most family and employment routes require a sponsor to file a petition first, then you file your own application after approval.
  • Processing times range from months to years depending on your category and country of birth, and visa availability changes annually.
  • You will need birth certificates, marriage certificates, police records, medical exams, and financial documents — the exact list depends on your route.
  • USCIS fees and biometric services fees apply to most routes; some people may be able to request a fee waiver based on income.

Family-based green cards and how sponsorship works

If a U.S. citizen or permanent resident relative is sponsoring you, the process happens in two stages. First, your relative files Form I-130 (Petition for Alien Relative) with USCIS. USCIS reviews this petition to confirm the relationship is real and that your relative can support you financially. Only after I-130 approval does your application move forward.

The second stage depends on where you are. If you're already in the United States, you file Form I-485 (Application to Register Permanent Residence or Adjust Status) with USCIS. If you're abroad, you go through consular processing — your case transfers to a U.S. embassy or consulate in your home country, where you attend an interview and complete the medical exam. The I-130 approval alone does not make you a permanent resident; it clears the way for your own application.

Wait times for family petitions vary by relationship and country. Immediate relatives of U.S. citizens (spouse, unmarried child under 21, parent of a U.S. citizen over 21) usually have no visa wait — their I-130 can move to the next stage as soon as it's approved. Other family categories have annual visa limits and can have multi-year waits. Your relative's immigration attorney or the USCIS website can tell you the current wait for your specific category.

Employment-based green cards and labor certification

Employment-based green cards require your employer to sponsor you. Most routes involve a step called labor certification, where your employer must show that no available U.S. worker can do your job at the prevailing wage. Your employer files Form ETA 9089 (Application for Permanent Employment Certification) with the Department of Labor, not USCIS. This step alone can take a year or more.

After labor certification approval, your employer files Form I-140 (Immigrant Petition for Alien Worker) with USCIS. Once I-140 is approved, you file your own application — either Form I-485 if you're in the U.S., or you go through consular processing if you're abroad. Some employment categories (EB-1 for people with extraordinary ability, EB-2 for advanced degree holders with a national interest waiver) skip labor certification, but these are narrow categories with strict requirements.

Employment-based processing can take three to seven years from start to approval, depending on your category, country of birth, and current visa availability. Some countries face per-country caps that create backlogs lasting years. Your employer's immigration attorney should explain the timeline for your specific situation before you begin.

Diversity visa lottery and how to enter

The diversity visa program makes 50,000 green cards available each year to people from countries with low immigration to the United States. You enter by submitting an online form during the registration period, usually in October. The form is free. USCIS randomly selects winners from all entries received.

If you're selected, you receive a notification letter. You then file Form I-485 (if you're in the U.S.) or go through consular processing (if you're abroad). You must complete this step within the fiscal year — if you don't, your visa number expires and you lose your selection. Processing times are compressed because of the annual deadline, so winners typically receive a decision within months, not years.

Diversity visa winners must meet the same health, security, and financial requirements as other applicants. You'll need a police certificate from every country you've lived in for more than six months, a medical exam by a USCIS-approved doctor, and proof that you won't become a public charge (usually a Form I-864 Affidavit of Support from a sponsor).

Refugee and asylee pathways to permanent residence

If you've been granted refugee or asylee status, you can file for permanent residence after one year. Refugees file Form I-485 one year from the date they were admitted to the United States. Asylees file one year from the date their asylum was granted. This is a simpler process than other green card routes because you've already passed security and health screening.

You still need to file Form I-485 and attend a USCIS interview, but the medical exam and security background check are usually waived because they were completed when you received refugee or asylee status. Processing typically takes four to six months. You'll need your refugee or asylee approval notice, passport, and any state ID or travel documents.

Documents you'll need and how to gather them

Every green card application requires certain core documents: a valid passport, birth certificate, marriage certificate (if applicable), divorce decrees (if applicable), and police certificates from every country you've lived in for more than six months. You'll also need a medical exam completed by a USCIS-approved civil surgeon — this is not your regular doctor, and you must use someone on the USCIS list.

Depending on your route, you may also need: Form I-864 (Affidavit of Support) from a sponsor showing they can support you financially; tax returns and pay stubs from your employer or sponsor; employment letters; educational diplomas; and proof of any prior immigration status (visa stamps, I-94 cards, previous green cards). If you're adjusting status in the U.S., you'll need proof of how you entered the country and your current immigration status.

Birth certificates and other vital records from your home country often require certified translations into English. Some countries charge fees for police certificates or take weeks to issue them. Start gathering documents early — delays here are one of the most common reasons applications stall. Keep originals and make copies; USCIS will ask for originals at your interview.

Fees, biometrics appointments, and what happens after you file

USCIS filing fees vary by form and route. Form I-485 costs around $640 for adults (fees change annually and vary by age). Form I-130 costs around $435. Form I-140 costs around $715. Some people with income below the federal poverty line may be able to request a fee waiver using Form I-912, though approval is not may provide and the waiver does not cover biometric services fees.

After you file, USCIS sends you a notice with a biometrics appointment date. You go to a USCIS Application Support Center, where they take your fingerprints, photograph, and signature. This appointment is mandatory. If you miss it without rescheduling, your application may be denied. The biometrics fee is separate from the filing fee and is not waivable.

After biometrics, USCIS conducts a background check. If you're adjusting status in the U.S., you'll receive a notice for your green card interview. If you're going through consular processing, your case transfers to the embassy or consulate in your country, and they'll contact you with an interview date. The interview is where you answer questions about your application, your relationship to your sponsor (if applicable), and your background. Bring all original documents and any additional evidence USCIS requested.

Processing times and what affects how long it takes

Green card processing times range from four months to several years, depending on your category and country of birth. Family-based immediate relatives typically see decisions within 12 to 18 months. Employment-based cases often take three to seven years because of labor certification and visa availability. Diversity visa winners must complete processing within the fiscal year, so they move faster but face a hard deadline.

Country of birth affects wait times significantly. Some countries face per-country visa caps, meaning applicants from those countries wait longer even if their category is otherwise fast. India and China, for example, have multi-year backlogs for employment-based green cards. USCIS publishes visa bulletin updates monthly showing current wait times by category and country.

Processing can also slow if USCIS requests additional evidence (called a Request for Evidence or RFE). This happens when documents are missing, unclear, or inconsistent. Respond to an RFE within the deadline given — usually 84 days — or your application may be denied. Many applicants work with an immigration attorney to avoid RFEs by submitting complete applications the first time.

Frequently Asked Questions

Can I work while my green card application is pending?

If you file Form I-485 in the United States, you can apply for work authorization (Form I-765) at the same time. USCIS can approve work authorization while your green card application is still pending, usually within two to three months. If you're going through consular processing abroad, you cannot work in the U.S. until your green card is approved and you enter the country.

What happens if my green card application is denied?

USCIS sends a notice explaining the reason for denial. You may be able to appeal using Form I-290B (Notice of Appeal or Motion) within 33 days of the denial notice. Not all denials are appealable — some are final. An immigration attorney can review your denial notice and tell you whether an appeal is possible and whether it's likely to succeed.

Do I need an immigration attorney to file for a green card?

You are not required to hire an attorney, but many people do because the process is complex and mistakes can delay approval or cause denial. An attorney can help you gather documents, avoid common errors, and respond to requests for evidence. Some nonprofits offer low-cost or free immigration legal services if you cannot afford a private attorney.

What is the difference between adjustment of status and consular processing?

Adjustment of status (Form I-485) happens in the United States — you file with USCIS and attend your interview at a USCIS office. Consular processing happens abroad — your case goes to a U.S. embassy or consulate in your home country, and you attend your interview there. You can only adjust status if you're already in the U.S. in a valid immigration status or fall into certain exceptions.

Can I travel while my green card application is pending?

If you're adjusting status in the U.S., you can travel abroad only if you have advance parole (Form I-131 approval). Without it, leaving the U.S. may be seen as abandoning your application. If you're going through consular processing, you must stay in your home country or the country where your consulate is located until your interview is complete and your green card is issued.
